My 4 chassis fans are connected to the Phanteks Evolv X fan hub. On the hub the first fan pin connector detects the RPMs of all the fans connected to it. This first fan spins at a different speed. This behavior goes away if I go into fan Xpert and run them at full speed then back to standard. At first I thought it was the fan but then swapped some fans around and its always on that connector that detects the speeds. Anyone ever experience anything like this? Could this be an issue with the fan hub?
